Frequently Asked Questions
What is a next-generation firewall (NGFW)?
A next-generation firewall combines traditional stateful packet filtering with deeper inspection features such as application awareness, intrusion prevention, TLS inspection and threat intelligence, so it can enforce policy on applications and users rather than only on ports and IP addresses.
What is the difference between an NGFW and firewall as a service (FWaaS)?
An NGFW is typically a hardware or virtual appliance that you deploy and manage at a site or data center. FWaaS delivers the same inspection and policy enforcement from the cloud, usually as part of a SASE platform, which removes the need to operate appliances at every location.
Do I need a separate firewall in the public cloud?
Cloud providers offer security groups and basic network controls, but dedicated services such as AWS Network Firewall, Azure Firewall and Google Cloud Firewall add centralized policy, deeper inspection and logging. Many organizations also deploy their existing NGFW vendor's virtual appliances in the cloud for consistent policy.
